Eh, what do you define as "grit?"
For example, I would definitely say that John Wick is not grit. Hyper-stylized violence (here, derivative of Hong Kong gun-fu) is not at all gritty to me. It varies between exciting, artistic, and, at times, comedic. As in "so-over-the-top" it becomes funny.
Gritty, to me, is real violence. Eastern Promises. The Road. A History of Violence. You know, films with Viggo Mortensen.
Well, others too. But if you have movies like Wick, or Crank, or Ong Bak* or even the Raid ... I don't consider those gritty.
